Getting blood work done at urgent care: What to expect

Urgent care is well-known for treating injuries and infections, but many people don't realize it can also be a fast and convenient option for blood work. Whether you need a CBC to investigate fatigue, a metabolic panel to check your kidney function, or routine cholesterol testing, urgent care can often handle the order and draw in a single visit — no appointment needed and no referral required.

If you're new to urgent care, it helps to understand what urgent care centers do — they sit between a primary care office and an emergency room, offering same-day evaluation for a wide range of non-life-threatening concerns, including lab testing.

What blood tests can urgent care do?

The specific tests available depend on the clinic's equipment, but most urgent care centers can order or perform:¹

• Complete Blood Count (CBC) — checks red cells, white cells, and platelets; used to screen for anemia, infections, and clotting disorders
• Basic Metabolic Panel (BMP) — evaluates kidney function, electrolytes, and blood glucose
• Comprehensive Metabolic Panel (CMP) — includes everything in a BMP plus liver function tests
• Lipid panel — measures cholesterol and triglycerides
• Thyroid panel (TSH, T3, T4) — checks thyroid hormone levels
• HbA1c — measures average blood sugar over 3 months; used for diabetes monitoring
• STI blood tests — HIV, syphilis, hepatitis B and C
• Pregnancy test (serum hCG)
• Mono test, strep confirmation

Some clinics can also run point-of-care tests for drug screening, cardiac enzymes, D-dimer, and more. Call ahead to confirm if you need a specific test.

Do you need a doctor's referral?

No. One of urgent care's advantages for blood work is that the provider evaluates you on the spot and orders whatever tests are clinically appropriate — without the delay of scheduling a primary care appointment. If you arrive with symptoms like fatigue, unexplained weight changes, or swelling, the provider can order the relevant labs during your visit.

If you already have a lab order from another provider and just need a draw, some urgent care centers offer phlebotomy-only services — call ahead to ask.

How to prepare for blood work at urgent care

Fasting requirements

Fasting is required for some tests and not others. Plan to fast for 8–12 hours before your visit if you expect to need:²

• Fasting glucose or insulin levels
• Lipid panel (cholesterol)
• Some comprehensive metabolic panels

Fasting is generally not required for CBCs, thyroid panels, HbA1c, STI tests, or mono/strep confirmation tests. Water is fine to drink before any blood test. If you're unsure, call the clinic before you go.

What to bring

• Insurance card and photo ID
• List of current medications (some drugs affect lab values)
• Any prior lab results you want compared
• Lab requisition slip if you already have one from a different provider

How long do results take?

Turnaround time depends on whether tests are processed in-house or sent to a reference laboratory:¹

• In-house analyzer (CBC, BMP/CMP, urinalysis, rapid glucose): results available within 1–2 hours, often before you leave
• External reference lab (lipid panel, thyroid, HbA1c, STI panels): typically 1–3 business days

Ask at check-in which of your requested tests will be done in-house and which will be sent out. This affects both when you get results and potentially how they're billed.

How much does blood work cost at urgent care?

Blood test costs are usually billed separately from the base urgent care visit fee. Approximate self-pay ranges:³

• CBC: $30–$75
• BMP: $35–$75
• CMP: $40–$100
• Lipid panel: $30–$100
• Thyroid (TSH): $50–$150
• HbA1c: $30–$80
• HIV test: $25–$75

One of the most frequently ordered panels at urgent care is the basic metabolic panel, which checks kidney function, electrolytes, and blood sugar in a single draw.

If you're paying out of pocket, see our breakdown of how much urgent care costs without insurance, including typical add-on fees for blood draws and lab panels.

With insurance, most medically necessary blood tests are covered subject to your deductible and coinsurance. If labs are sent to an external facility, you may receive a separate bill from that lab — sometimes weeks later.

Getting your results

For in-house tests, the provider typically reviews results with you before you leave. For external labs, most urgent care centers contact you by phone or notify you through a patient portal when results are ready. Ask at check-in how you will be notified. If you want results shared with your primary care provider, request that in writing at registration.
